Specification of Letters Patent.

Patented Sept. 3, 1907.

Application filed Tune 22 1905. Serial No. 266,398-

To all whom it may concern:

Be it known that I, EPPA H. RYON, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts, have invented I certain new and useful Improvements inSwivel- Looms, of which the following is a specification.

My invention relates to swivel looms in which, in addition to theordinary fly shuttles, swivel shuttles are used to weave spots orfigures on the fabric in the well known way, and to that class of swivellooms in which two or more sets of swivel shuttles are used, and inwhich each set of swivel shuttles may have a different colored thread,and my invention more particularly relates to certain novel features ofconstruction of the several 1 5 parts of the swivel shuttle mechanism ofa swivel shuttle loom.

The object of my invention is to improve upon the construction of swivelshuttle looms, as ordinarily made, and to provide swivel shuttlemechanism of improved construction and operation, and my inventionconsists in certain novel features of construction of my improvements aswill be hereinafter fully described.

I have only shown in the drawings detached parts of a swivel shuttleloom with my improvements applied thereto, suflicient to enable thoseskilled in the art to understand the construction and operation thereof.

Referring to the drawingsz-Figure 1 is an end view of the left hand sideof a loom frame, showing the operating mechanism of the swivel shuttlerail on the outside of the loom frame, and the swivel shuttle rail inits outward raised position; the broken lines show the swivel shuttlerail in its inward lowered position. Fig. 2 is a sectional view, lookingfrom the inside of the loom frame, and showing some of the parts notshown in Fig.

Fig. 4 is asection, on line 4,4, Fig. 2, looking in the direction of arrow b, same figure. Fig. 5shows the operating mechanism of the crank shaft for the swivel shuttlebar, shown at the left in Fig. 1., and also shows the sliding pickmotion. Fig. 6 is a rear view of the parts shown in Fig. 5, looking inthe direction of arrow 0, same figure. Fig. 7 is a plan view of themutilated gear mechanism, shown in Fig. 5, looking in the direction ofarrow d, same figure. Fig. 8 is a plan view of the driving mechanism ofthe swivel shuttle racks, looking in the direction of arrow 6, Fig. 9.Fig. 9 is a front view of the parts shown in Fig. 8, looking in thedirection of arrow f, same figure; some of the parts shown in Fig. 8 arebroken away in this figure. Fig. 10 is an end view of the parts shown inFig. 9, looking in the direction of arrow 9, same figure. Fig. 11 is arear view of the parts shown in Fig. 10, looking in the direction ofarrow h, same figure; some of the parts shown in Fig. 10 are left off inthis figure. Fig. 12 shows a front view of the swivel shuttle-rail,detached, and partially in section, with the swivel shuttles extendingin a horizontal plane, and, Fig. 13 is a section on line 13, 13, Fig.12, looking in the direction of arrow 2', same figure. Figs. 4 to 13,inclusive, are shown on an enlarged scale.

In the accompanying drawings, 1 is the left hand loom side or frame, 2is the laysword, pivotally mount ed at its lower end and carrying thelay-beam 3, reed 3, and hand-rail 3. The lay-sword 2 is connectedthrough a crank connector 4 to the crank shaft 5, in the ordinary way,see Fig. 2. The picking shaft 6, Figs. 5, and 6, is mounted in suitablebearings on the loom frame, and carries the picking arm 7 fast thereon,having a stud 7 on which is mounted the picking roll 7", in the usualway. I 7 0 I will now describe my improvements.

Near the end of the crank shaft 5, in this instance on the outside ofthe loom frame, is fast a gear 9, Figs. 1 and 2, which meshes with agear 10, see Fig. 7 loosely mounted on a stud 11 fast in a stand 12, onthe loom side 7 5 1, see'Fig. 2. The gear 10 is connected with a gear10, mounted on the stud 11, said gear 10 has a portion of its periphery10* without teeth, see Fig. 5, to give a dwell motion to a third gear13; said gear 13 is in line with the gear 10 see Fig. 7, and is withoutteeth for a portion of its periphery. A clutch 14 has its hub looselymounted on the extended end of a second crank shaft 15 suitablyjournaled on the loom frame, and is provided with an annular groove 14.therein to receive the pins on the forked end of an angle or bell cranklever 16, the hub 16 of which is pivotally mounted on a stud in an arm16, see Fig. 5. The other arm of the angle lever 16 has attached theretothe lower end of a connector 17.

A spring 1.8, attached to the angle lever 16 and to the frame, acts tohold the clutch 14 in its outward position.

The clutch 14 has two side projections 14 thereon, which extend intoopenings in the gear 13, and act to hold the clutch in proper positionrelative to the gear. The clutch 14 has an engaging arm 14 extending outtherefrom, which, when the clutch 14 is in its outward or inoperativeposition, is adapted to engage a stop 14 on the inside of the stand 1,shown by dotted lines in Fig. 5, and also shown in Fig. 7 to stop therotary movement of the clutch 14, and parts connected therewith. Whenthe clutch 14 is moved inwardly, through the operation of the jacquardmechanism, not shown, acting through the connector 17, the arm 14 on theclutch will be moved out of the path of the stop 14 and into the path ofthe starting tooth 10 secured to the mutilated gear 10, so that therevolution of said gear 10% through the revolution of the gear 10 andgear 9 on the driven crank shaft 5, will, through the starting tooth 10engaging the arm 14 on the clutch 14, rotate 'ing rod 23.

said clutch, and cause the rotation of the gear 13, until the teeth 10on the gear 10 mesh with the teeth on the gear 13, and cause said gear13 to rotate.

The gear 13 is loosely mounted on the crank shaft 15, and carries a pin13, actuated by a spring 13, see Fig. 6, to yieldingly hold the end ofthe pin 13 in a recess in a plate or disk 20, which is adjustablysecured on the shaft 15 by a screw 20, see Fig. 6, to yieldingly connectthe gear 13 through disk 20 with the shaft 15, and cause said shaft 15to rotate with the gear 13, and the spring actuated pin 13 forms agive-way device, so that in case of accident to the swivel shuttlemechanism, the pin will yield, allowing the shaft 15 to remain at rest,and thus prevent breakage.

The crank shaft 15 has two cranks therein, one of which, 15, is shown inFig. 2. Each crank 15 is connected, through a crank connector 21, withayoke 22, which has bosses 22 mounted on a longitudinally slid- A collar24, secured on the rod 23 by a set screw 24, extends between the bosses22 of the yoke 22, and acts to hold the yoke 22 in place on the rod 23.The rod 23 is mounted at its rear end in bearings 25 on a I stand 25,secured to the loom frame, see Fig. 2, and at its forward end is, inthis instance, supported on a grooved roller 26 mounted on a stud 27 onthe stand 27. A pin 28 extends over the rod 23, see Fig. 4.

On the forward end of each rod 23 is a yoke 29, having bosses 29 mountedon the rod 23. A collar 29 on the rod 23 extends between the bosses 29on the yoke 29, and is secured in place by a set screw 29, and securesthe yoke 29 in place on the rod 23, see Fig. 2. The two yokes 29, one oneach rod 23, at opposite ends of the loom, support two longitudinalparallel rods 30, on each of which, at each end, (only one end is shownin the drawings,) is mounted a hub 31 on a bracket 31 see Fig. 9. Thelower end of the bracket 31 has secured thereto the end of the shuttlerail 32, see Fig. 10.

Through the rotation of the crank shaft 15, at predetermined intervals,and for a predetermined length of time, according to the indications ofthe pattern mechanism, through the operation of the gears 9, 10 and 13,and the clutch mechanism above described, a longitudinal motion iscommunicated to each rod 23, at each end of the loom, through the crankconnectors 21, to carry the swivel-shuttle-rail 32, and the swivelshuttles 33 supported thereon, from its forward or outer position, whenthe lay is in its rear position, as shown in Fig. 1, to its rearposition, as shown by dotted lines in Fig. 1, when the lay is in itsrear position, and in which position the swivel shuttles are operated toweave figures or spots on the fabric.

I will now describe the mechanism for communicating a longitudinalmotion to the swivel shuttle-rail 32, carrying all the swivel shuttles33, to vary the position of the spots or figures on the fabric, in thedirection of the width of the fabric.

On the outer end of the crank shaft 5 is fast a cam 34, which is adaptedto engage a projection 35 on a cam lever 35 pivoted on a stud 35 on thestand 1, see Fig. 5. The lever 35 has pivotally attached to its frontend a link 36, connecting said lever 35 with one arm of a bell cranklever 37, pivotallymounted on a stud 38, see Fig. 1. The other arm ofthe bellcrank lever 37 carries a pawl 39, which is adapted to engage andturn a ratchet wheel 40, attached to a gear 41 loose on a stud 42. Afriction device, comprising in this instance two jaws 43, mounted on thestud 38, and held in yielding engagement by a spring 44, with the hubportion of the ratchet 40, acts to yieldingly hold said ratchet and thegear 41. The gear 41 meshes with and rotates a gear 45 loosely mountedon a stud 46. Connected with the gear 45 is a disk 47, carrying patternpins or indicators 48, of different lengths, see Fig. l. A disk 49carrying pattern pins or indicators 50, see Fig. 2, is connected to thegear 41. The pattern pins on the disks 47 and 49 are adapted to engage acam projection 51 011 a bar 51, which has slots therein, through whichthe studs 42 and 46 extend, see Fig. 2, to support said bar. The bar 51is moved into different positions, in this instance into three differentpositions, by the pattern pins 48 and 50, and through intermediatemechanism to be described, causes the swivel shuttle-rail 32 to be movedinto three different positions.

The lower end of the bar 51 has a pin 51 thereon,

to which is pivotally attached the upper end of a link 52, see Fig. 4,the lower end of the link 52 is attached to a lever 53, the hub 53 ofwhich is loosely mounted on one of the rods 23, see Fig. 2, between thebearings 25 on the stand 25. Extending up from the hub 53 is an arm 53,see Fig. 2, the upper end of which is forked or recessed, see Fig. 4, toreceive a rod 53", the ends of which are secured in the ends of arms53", the hubs 53" of which are fast on the rod 23, see Fig. 2.

The turning of the hub 53, through the vertical movement of the bar 51,see Fig. 2, will, through rod 53 and arms 53, turn the rod 23, andthrough the collar 54 fast on said rod, and the arm 55 pivotally mountedin the yoked shaped extension 54 on said collar 54, see Fig. 9,communicate a longitudinal motion to the connector 56, having adownwardly extended slotted projection thereon, to which the lower endof the arm 55 is adj ustably attached by a bolt 57, the connector 56,attached at one end to the supporting bracket 31 of the shuttle rail 32,and at its other end to aprojection 58 on a collar 58, moves the bracket31 longitudinally on the supporting rods 30, and also the shuttle-rail32.

The rotary movement of the ratchet wheel 40, and the movement of the bar51, and through intermediate mechanism the longitudinal movement of theshuttle rail 32, is controlled by pattern mechanism.

In this instance the bell crank lever 37 has a pin 37 thereon, see Fig.1, which, when the lever 37 is in its raised position, and the cam lever35 on the highest part of the cam 34, is in position to be engaged bythe hooked end of a bell crank lever or latch 59, see Fig. 1, to holdthe cam lever 35 in its inoperative position. A spring 60, attached tothe lever 59 and to a stationary part, acts to hold the lever 59 inengagement with the pin 37. A cord 61, attached to the bell crank lever59, passes over a guide sheave 62 to the jacquard mechanism, not shown,and operates, on the indication of the jacquard mechanism, to move thelever 59 to disengage it from the pin 37 releasing the cam lever 35, anda1- lowing the cam 34 to operate said lever and cause the pawl 39 toturn the ratchet 40, and through intermediate connections communicatelongitudinal movement to the swivel shuttle-rail 32, as above described.

I will now describe the mechanism for moving the swivel shuttle-racksindependently of the movement of the swivel shuttle-rail.

, rear stand 72, see Fig. 8.

The swivel shuttlerail 32 carries a series of blocks or guides 32 seeFig. 13, which preferably have a metal back 32 which is made separatefrom and attached to the rail 32, and has studs 64 secured thereto, onwhich are mounted a series of pinions 64 for communicating motion fromthe reciprocating racks 63, to the swivel shuttles 33, in the usual andwell known way. In this instance there are three shuttle-racks 63, eachoperates through a system of pinions 64, the swivel shuttles 33 whichare shown in Figs. 12 and 13, extending horizontally. In case the swivelshuttles extend-in a vertical direction, as shown in the other figures,the racks 63 will operate the same through pinions, not shown, in theordinary way.

Each swivel shuttle-rack 63 has a sliding bar 65 connected therewith, inthe ordinary way, and each bar 65 is connected by a link 66 with a lever67, having a hub 67 mounted on a pin 68, supported in the upwardlyextending projections on the brackets 31, see Figs. 8, and 9. Each lever67 is connected by a rod 69 to the lower end of a lever 70, see Fig. 9,having a hub 70 mounted on a stud 71, supported in the upper ends of thestands 72, having hubs 72 at their lower ends mounted to slide on theparallel rods 30, see Fig. 10. Each lever 70 has a movement communicatedthereto, to communicate to the swivel shuttle racks a motion, to carrythem from one extreme position to the other, and move the swivelshuttles, through the rotation of a master gear 73; loosely mounted on astud 74, supported in the stands 72, and having a cam groove 73 thereinto receive a pin 70 fast in each lever 70, see Fig. 1]..

Each one of the three master gears 73 has a partial rotationcommunicated thereto, at predetermined intervals, by a mutilated pinion76, Fig. 9, fast on a longitudinally sliding shaft 7 7, mounted insuitable bearings 7 2 on the stands 72. On the shaft 7 7 is splined apinion 78, to rotate said shaft 77 and allow said shaft to movelongitudinally. A pinion 79 on a sleeve 79, mounted on a stud secured tothe inner stand 72, see Figs. 1 and 10, meshes with and rotates thepinion 78 and the shaft 77. The forked end of the sleeve 79 is pivotallyconnected with a head 80 on the forward end of a shaft 80, see Fig. 10.The rear end of the shaft 80 is pivotally connected through a connection81 with the forward end of a square or non-circular shaft 82, seeFig. 1. The rear end of the shaft 82 extends loosely through a bearing83 on a stand 83 secured to the stand 1 on the loom frame, see Fig. 1,so as to have a longitudinal motion in said bearing, as the swivelshuttle rail moves back and forth.

On the shaft 82 is a bevel gear 84, which rotates with the shaft 82, butis prevented from moving longitudinally with said shaft by extendingbetween the bearings 83. The bevel gear 84 meshes with and is driven bya bevel gear 85 fast on one end of the crank shaft 15, see Fig. 6.. Alongitudinal motion is communicated to the shaft 77 carrying themutilated pinion 76, through a lever 86 centrally pivoted at 86 on astand 87, secured to the The lever 86 is forked at one end and has pinsthereon which extend into an annular groove 87 in a collar 87 fast onthe shaft 77 see Fig. 10. The other end 'of the lever 86 has a pin 86thereon which extends into a cam groove 88 in a plate 88 on the upperend of an arm 88 extending up from a collar 88 see Fig. 11, loose on astud, said collar has a forked end attached to a swivel block 88, whichblock is also pivotally connected to a second fork fast on the end of ashaft 89. The shaft 89 is splined at its inner end in a hub 90 on aconnection90, see Fig. 1, to have a rocking motion with'said connection,and also a longitudinal motion in said hub 90, as the swivel shuttlerail moves back and forth.

The inner end of the connection 90 has in this instance a ball andsocket joint connection 90, with a stationary part of the frame, seeFig. 1, and an arm 90 extending out therefrom, see Fig. 3, to which isat tached a cord 91 leading to a lever 92, see Fig. 1, which isconnected at its ends, through links 93, to levers 94 and 95, havinghubs 94 and 95, pivotally mounted on a stud 96, and arms 97 and 98extending from said hubs, and connected to the jacquard mechanism, notshown. Through the jacquard mechanism, and the connections to theconnection 90, said connection and the shaft 89 is rocked, to move theplate 88 into three dif ferent positions, and in each of said positions,through the lever 86, the shaft 77 will be moved longitudinally to bringthe mutilated pinion 76 in line with one of the master gears 73, andturn said gear a partial rotation, the other two master gears 73 beingheld stationary by the drums 99, on the shaft 77, see Figs. 8 and 1.0,engaging the blank spaces or dwell portions on the master gears 73.

At the time of the operation of the swivel shuttles, the picking motionof the fly shuttle, not shown, will be stopped, in any usual manner.

In this instance a cam 100, fast on the crank shaft 15, operates a camlever 101, centrally pivoted at 102, and attached at its lower end bythe collar 103 to a sliding rod 104, having fast thereon a forked arm105 which engages an annular groove in the hub 7 of the picking lever 7carrying the picking roll-7, see Figs. 5 and 6. The picking roll 7 ismoved out of and into engagement with the picking shoes, not shown.

From the above description in connection with th drawings the operationof my improvements will be readily understood by those skilled in theart. By means of the two crank motions one for the lay, and one for theswivel shuttle rail, the swivel shuttle rail will remain stationaryduring the operation of the fly shuttle andthe backward and forwardmovement of the lay. When the jacquard mechanism indicates, the swivelshuttle-rail, through the rotation of the crank 15 and the longitudinalmovement of the sliding rods 23, will be moved .back and forth, to carrythe shuttles into and out of operative position, and the swivelshuttle-rail, carrying all the swivel shuttles, will be movedlongitudinally at predetermined times, according to the indications ofthe jacquard mechanism, and each set of shuttles will be movedindependently, according to the indications of the jacquard mechanism.

It will be understood that the details of construction of myimprovements may be varied if desired.
